PERL values Function

Syntax

Definition and Usage

Returns the list of all the values contained in HASH. In a scalar context, returns the number of values that would be returned. Uses the same iterator, and therefore order, used by the each and keys functions.

Check keys() function also

Return Value

• In scalar context - Number of values in the hash

• In list context - List of values

Example

#!/usr/bin/perl -w

%hash = ('One' => 1,
         'Two' => 2,
         'Three' => 3,
         'Four' => 4);

@values = values( %hash );
print("Values are  ", join("-", @values), "\n");

@keys = keys( %hash );
print("Keys are ", join("-", @keys), "\n");

It will produce following results:

Values are  4-3-2-1
Keys are Four-Three-Two-One
